双频激电法在河南某钼矿带进行快速找矿评价中的应用

摘要

文章主要介绍了运用双频道激发极化法在河南省豫西山区进行快速找矿工作中发现矿体的过程及在野外施工过程中应注意的几个问题.通过双频激电中梯测量,在工作区圈定了3处激电异常,通过该区地质资料,岩(矿)石物性特征以及化探次生晕资料对激电异常进行了综合研究分析,经过钻探验证,此异常与隐伏钼矿体和钼矿化有关.证明了双频激电法完全能适应在豫西山区进行快速找矿评价,并取得良好的效果.%This paper mainly deals with the process of using dual-frequency induced polarization in rapid exploration of the mountain area of western Henan Province with the purpose of finding ore bodies and the problems worthy of attention in the field engineering.Through dual -frequency?induced polarization intermediate gradient survey, three induced polarization anomalies in the working area was discovered.An integrated analysis of the induced polarization anomalies was also made on the basis of local geological data,physical properties of rocks and geochemical secondary halos.Drilling has proved that the anomalies are related to concealed molybdenum ore bodies and molybdenum mineralization.It is also proved that dual-band induced polarization can be fully adapted to the rapid exploration and evaluation of the mountain area of western Henan Province with good results achieved.
